1. Ride up to the object at a slight angle at any speed that feels comfortable.
2. You have to ollie high and almost 180 over the object. So you want your feet in the same position for a 180.
3. Ollie, turn, and land on the object with your weight centered.
4. Getting off is the same as a boardslide, either finish the 180 or turn back to the way you started.
